OMC-IDS : at the cross-roads of OLAP mining and intrusion detection

International audienceDue to the growing threat of network attacks, the efficient detection as well as the network abuse assessment are of paramount importance. In this respect, the Intrusion Detection Systems (IDS) are intended to protect information systems against intrusions. However, IDS are plugged with several problems that slow down their development, such as low detection accuracy and high false alarm rate. In this paper, we introduce a new IDS, called OMC-IDS, which integrates data mining techniques and On Line Analytical Processing (OLAP) tools. The association of the two fields can be a powerful solution to deal with the defects of IDS. Our experiment results show the effectiveness of our approach in comparison with those fitting in the same tren

Formal Concept Analysis in Knowledge Discovery: A Survey

In this paper, we analyze the literature on Formal Concept Analysis (FCA) using FCA. We collected 702 papers published between 2003-2009 mentioning Formal Concept Analysis in the abstract. We developed a knowledge browsing environment to support our literature analysis process. The pdf-files containing the papers were converted to plain text and indexed by Lucene using a thesaurus containing terms related to FCA research. We use the visualization capabilities of FCA to explore the literature, to discover and conceptually represent the main research topics in the FCA community. As a case study, we zoom in on the 140 papers on using FCA in knowledge discovery and data mining and give an extensive overview of the contents of this literature.status: publishe
